The curve y = x2 is a parabola. It is symmetric about y-axis and has its vertex at (0, 0) and the curve y = 2/(1 + x2) is a bell shaped curve, x-axis is its a symptote and it is symmetric about y-axis and its vertex is (0, 2).
Therefore, coordinates of C are (-1, 1) and coordinates of B are (1,1 ).
The required area is OBACO = 2 area of curve OBAO
